Google's shiny new AI powered results are sometimes terribly wrong, because the algorithm misinterprets satire or jokes as factual information. There doesn't seem to be any real problem with the automated summarization process per se, taking a text and transforming it into another text that's shorter. But the things it's... Continue reading

We systematically underestimate the difference between an enormous pile of words and a coherent extended narrative. You type and type and type and answer a bunch of questions and contribute your hot takes and all of that. Then you look at that word pile and think "gee, I wrote a... Continue reading

Rather than post a reply to a thread I will start one here. It's always best to be at the top of the page. Never read the comments. Not everything that someone else types into a little rectangle deserves a reply, even if you have one handy. Networks that are... Continue reading

A trip report from Hamvention 2024 while it's still fresh in the mind. The ARROW bus from Ann Arbor was a success thanks to AC8TO who stepped up as cruise director. It was nice not to have to drive. We assembled at 430a in Ann Arbor, and stopped in Toledo... Continue reading
See for the commit message. "Ext2 users are advised to use ext4 driver to access their filesystem. The driver is fully compatible, supports filesystems without journal or extents, and also supports larger time stamps if the filesystem is created with at least 256 byte inodes." Continue reading

I didn't need that account anyway. Add "takeover by a large language model" as one more way for an online community to die, to go with "takeover by Nazis", "overrun by spammers", and "starved by previously generous advertisers". Continue reading

If you enjoy any of these parts of the hobby in the presence of a purist, you'll get the dismissive reply that these are "not real ham radio". * Digital voice modes. DMR, D-Star, YSF etc get rejected because they use the Internet to interconnect repeaters. * Packet radio, because... Continue reading

I gave a talk at Penguicon 2024 about the Epochalypse (year 2038 bug). The discussion after the event made me think I should keep at this for at least some of the next 14 years, looking at timekeeping related issues. Mostly this is a clippings blog, with references back to... Continue reading

From > Since 2008, instead of applying leap seconds to our servers using clock steps, we have "smeared" the extra second across the hours before and after each leap. The leap smear applies to all Google services, including all our APIs. A software library for managing this is "unsmear" which... Continue reading

From Nature, 27 March 2024 > Humans’ effect on the polar ice sheets is slowing Earth’s rotation, posing challenges for its alignment with the official time standard. Two researchers discuss the science behind the slowdown and the impact it has on timekeeping. The leap-second problem in question is the "negative... Continue reading

From as seen on 2024-04-29 : > This is now less that 15 years away and plenty of system that will have problems have already been shipped. We should stop adding to the problem. Most computing, especially computing using Debian or its derivatives, is now done on 64-bit hardware where... Continue reading

From dated April 2 2024: > A unified time standard—Coordinated Lunar Time (LTC)—will act as the established standard to enable cislunar operations and can be tied to Coordinated Universal Time (UTC), the primary time standard globally used to regulate clocks and time on Earth. This policy directs NASA to work... Continue reading

A meme. Not my original work, forwarded to me by benny Vasquez. "Describe your perfect date." "Oh that's a tough one. I'd have to say YYYY-MM-DD, because when you sort it alphabetically it also sorts it chronologically." Continue reading

CHIRP is a versatile tool for programming your amateur radio. It supports dozens of radio models and has a straightforward and largely vendor-independent way to get a new radio up and running. A few years back there was a workshop at the All Hands Active maker space in Ann Arbor... Continue reading
I went with members of the University of Michigan Amateur Radio Club and the ARROW club to Findlay, Ohio for the total eclipse. The eclipse itself was fantastic - the sudden darkness, the eerie lack of shadows, the bright horizon, and the fabulous corona around the disk of the moon.... Continue reading
Previously: 2022, 2020, 2019, 2018 Ball games are shorter now, with the combination of the pitch clock and the free runner in extra innings combining to make games closed to 2 hours than 3 hours. This means that late night baseball from the west coast might be done by midnight... Continue reading
My usual ADS-B antenna these days is a mag mount whip, stuck to either a cookie sheet or a curtain rod. It will typically get good coverage with an indoor placement near a window of 60-80 nm range. To my mind that is adequate but not exceptional. I asked myself... Continue reading
"Keep the internet weird" is a difficult challenge. I think Mastodon helps in that aspect, at least now. Having a communications channel that is not entirely centrally owned and controlled means that you can have parts of it that are quirky. The world of obscure self-hosted software running in homelabs... Continue reading

My homelab principles: One Pi, one project. Limit the number of things you want to mess with. Dedicate hardware to each. Don't ever build anything that depends on an SD card lasting until tomorrow. If you get bored with a project, re-image the media and repurpose the hardware to something... Continue reading

The first computer-generated music I ever heard up close was from an AM radio next to an 8080 machine. Tune to the correct frequency, run a program, hear "Daisy Daisy" on the radio. This was in the mid-1970s at the Michigan Tech University's "Summer Youth Program", a week-long class on... Continue reading

Successful activation of AA-001 Allmendinger Park this morning, 2024-02-26, for the 800a weekday morning roundtable net on the N8DUY repeater 145.15-. Allmendinger Park is just west of Michigan Stadium and covers roughly four city blocks. There is a play area in the NW corner, and the photo shows my N9TAX... Continue reading
I wanted to write something on Mastodon in response to something else, but people sometimes get bent out of shape about random people in their mentions. If you don't mention them it's a subtoot and that sounds bad too. If you listen to too many people complain too long, it... Continue reading
